what is [Ag^+] in a solution formed by mixing 25.0 ml of 0.10 M AgNO3 with 50.0 ml of 1.50 M Na3PO4. Ksp for Ag3PO4=1.0x10^-21

1) 2.34g of sodium chloride was dissolved in 250cm3 of water. What is the concentration of the sodium chloride solution in mol/dm3 ?
2) When 0.05 mole of oxygen gas reacts with 0.05 mole of hydrogen gas, steam is formed. What would be the remaining volume of gases measured at r.t.p. ?

Balance the molecular equations based on the reactions you mixed together and write the complete ionic equations and net ionic equations for all of the reactions that you tested that gave you a precipitate. if you got "no reaction" because you did not get a precipitate, then write the ionic equation by listing the ions for all the aqueous solutions on the reactant side and then an ---> and the words "no reactions".
AgNO3(aq) + KCl(aq) -----> KNO3 + AgCl

Фn undergraduate student weighs 20g of sodium carbonate salt. Of Na =23, O = 16, Carbon = 12 and H = 1, what is the mole of the hydroxide?

In a typical titration experiment a student titrates a 5.00ml sample of formic acid with 26.59 ml of 0.1088 m naoh.At this point the indicator turns pink. Calculate the concentration of formic adic in the original sample.

Write the neutralization reaction for acetic acid reacting with sodium hydroxide.

Write the equilibrium dissociation reaction for acetic acid, and the expression for the equilibrium constant, Ka, which corresponds to this reaction.

What does it mean to say that an acid is a strong acid? How is a strong acid different from a weak acid?

​At room temperature, I2 exists as solid, Br2 exists as a liquid and Cl2 exist as a gas. Why do they exist as different states?

a student was asked to find the relative atomic mass of element X. crystals of the chloride of X were know to have the formular XCl2 .6H2O.the student dissolved 2.03g of the crystals in water, and then added an excess of silver nitrate solution to the solution formed. a white percipitate of silver chloride was formed, which was filtered, dried and weighed. 2.87g were formed. Ag+Cl---AgCl calculate: the number of moles of silver chloride formed? the number of moles of X chloride in the solution? the mass of 1 mole of XCl2.6H2O? the relative atomic mass of X?
